• Tinnitus Handicap Inventory (THI) The THI is a self-report measure that can be used in a busy clinical practice to quantify the impact of tinnitus on daily living. The measure is brief, easy to administer and interpret, broad in scope, and psychometrically robust. Convergent validity was assessed using another measure of perceived tinnitus handicap (Tinnitus Handicap Questionnaire). Construct validity was assessed using the Beck Depression Inventory, Modified Somatic Perception Questionnaire, symptom rating scales (annoyance, sleep disruption, depression, and concentration), and perceived tinnitus pitch and loudness judgments. The THI is comprised of 25-item items grouped into functional, emotional, and catastrophic subscales. The total scales yield excellent internal consistency reliability (Cronbach's alpha=.93).
